Abstract
The utility model relates to a rope dissociation prevention device for a tower crane. The rope dissociation prevention device comprises two fixing plates, wherein the two fixing plates are connected with the crane, are used for fixing a pulley block and are arranged one after the other; a first connecting shaft penetrates through the space between the two fixing plates; the pulley block is assembled on the first connecting shaft; the pulley block comprises a plurality of pulleys; the upper and lower part of each fixing plate are provided with lifting lugs; two corresponding lifting lugs front and back are connected through second connecting shafts; two ends of the second connecting shafts are fixed through opening pins; a rope dissociation piece is arranged between every two adjacent pulleys; another rope dissociation prevention piece is arranged on the outer sides of two pulleys on the outermost side; two ends of each rope dissociation prevention piece are respectively connected with two second connecting shafts; the rope dissociation prevention pieces are arc-shaped; the radiuses of the rope dissociation prevention pieces is greater than the radiuses of the pulleys. The rope dissociation prevention device has the advantages that a steel wire rope cannot be dissociated, the use is convenient, and the operation security of the tower crane is ensured.
Description
Technical field
The utility model relates to a kind of anti-off rope device for tower crane.
Background technology
The phenomenon that tower crane in use often there will be steel rope to deviate from from the grooving of pulley; after steel rope is deviate from from grooving; easily occur being stuck, the phenomenon such as extruding, cause steel rope to occur the damage situations such as fracture of wire, distortion, disconnected thigh, affected the safe operation of tower machine.Therefore, prevent the de-groove phenomenon of steel rope, to the great meaning of safety in production tool.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, provides a kind of assurance steel rope can not take off groove, easy to use, guarantees the anti-off rope device for tower crane of tower machine safe operation.
The purpose of this utility model is achieved through the following technical solutions: a kind of anti-off rope device for tower crane, comprise two adapter plates that place front and back that are connected with hoisting crane for dead sheave group, between two adapter plates, run through and be provided with the first adapter shaft, assembly pulley is enclosed within on the first adapter shaft, assembly pulley comprises a plurality of pulleys, the top and the bottom of each adapter plate are equipped with hanger, before and after by the second adapter shaft, be connected between corresponding two hangers, the two ends of the second adapter shaft are all fixed by spring cotter, between every adjacent two pulleys, be provided with Anti-rope drop part, the outside that is positioned at two pulleys of outermost is also provided with Anti-rope drop part, the two ends of each Anti-rope drop part are connected with two the second adapter shafts respectively, Anti-rope drop part is arc, the radius of Anti-rope drop part is greater than the radius of pulley.
Further improvement of the utility model is: described assembly pulley comprises three pulleys.
The utility model compared with prior art has the following advantages: easy to use, and can guarantee that by the both sides of using Anti-rope drop part to be placed on pulley steel rope can not take off from grooving, thereby guaranteed the safe operation of tower machine, guaranteed work efficiency, when not needing to use, pull out spring cotter, just can very easily anti-off rope device be taken off.
accompanying drawing explanation:
Fig. 1 is the front view of the utility model structural representation;
Fig. 2 is the birds-eye view of Fig. 1;
Number in the figure: 1-pulley, 2-adapter plate, 3-the first adapter shaft, 4-hanger, 5-the second adapter shaft, 6-spring cotter, 7-Anti-rope drop part.
the specific embodiment:
in order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 and Fig. 2 show the specific embodiment of a kind of anti-off rope device for tower crane of the utility model, comprise two adapter plates 2 that place front and back that are connected with hoisting crane for dead sheave group, between two adapter plates 2, run through and be provided with the first adapter shaft 3, assembly pulley is enclosed within on the first adapter shaft 3, assembly pulley comprises a plurality of pulleys 1, the top and the bottom of each adapter plate 2 are equipped with hanger 4, before and after by the second adapter shaft 5, be connected between corresponding two hangers 4, the two ends of the second adapter shaft 5 are all fixing by spring cotter 6, between every adjacent two pulleys 1, be provided with Anti-rope drop part 7, the outside that is positioned at two pulleys 1 of outermost is also provided with Anti-rope drop part 7, the two ends of each Anti-rope drop part 7 are connected with two the second adapter shafts 5 respectively, Anti-rope drop part 7 is arc, the radius of Anti-rope drop part 7 is greater than the radius of pulley 1, the preferred assembly pulley of the utility model comprises three pulleys 1.
The utility model can guarantee that by the both sides of using Anti-rope drop part 7 to be placed on pulley steel rope can not take off from grooving, thereby has guaranteed the safe operation of tower machine, has guaranteed work efficiency.
